Abstract: The most common method used for user security is textual passwords. But they are vulnerable to eves dropping, dictionary attack, shoulder surfing etc. To address this problem, text can be combined with colors to generate session passwords called hybrid textual authentication for authentication in multi – cloud. Provable data possession is a technique for ensuring data integrity. We present a cooperative provable data possession scheme based on homomorphic verifiable response and hash index hierarchy for ensuring integrity of data in cloud storage.
Keywords: Session passwords, Hybrid textual authentication, Multi-Cloud, Provable data possession, Cooperative provable data possession.
